relative to the partition of \(=(\theta ,)\) . When \(Q_n\)  is the negative log-likelihood function, and the dimension of the parameter is independent of \(n\) , then \(h(; )\)  given by (REF ) is called the efficient score function for \(\theta \) , and classical theory shows that it admits solutions that are consistent, asymptotically normal and attain the information bound given by the reciprocal of
(REF ) [1]}, [2]}.
